GTO SPEAKE

GRAND TOURING SERIES
For more than 60 years, JBL has been delivering products embodying the technology developed in the professional arena equipping leading recording studios and movie theaters, as well as live-music reinforcement in venues ranging from dance clubs to Woodstock. We continue to transform this expertise into products that provide the impact and excitement of a live performance. The JBL experience is for enthusiasts who wont settle for anything less than live at home or on the go.

LOW-Q WOOFER DESIGN

The lower Q offers higher bass output and better transient response in typical mounting locations (doors, rear package trays).

UNIPIVOT* TWEETER POD

Select JBL GTO models use a unique, patented rotating-tweeter design, which allows the installer or end user to aim the tweeter toward the sweet spot for optimal imaging.
INTERMOUNT III MOUNTING SYSTEM

PLUS ONE WOOFER CONES

Each GTO model uses a patent-pending woofer cone with more surface area than in competing models of the same size. The benefits are increased bass output and increased efficiency, both very audible and important.
REDUCED NOMINAL IMPEDANCE
Allows for installation of all 6-1/2" models in all four 6"-hole size standards without the need for additional adapters or installation kits.
BUILT-IN CROSSOVER NETWORKS
Thats right GTO speakers have 2-ohm voice coils. This enables them to extract all the power from amplifiers and head units that are designed to increase power when driving 2-ohm loads.
Most JBL GTO speaker models come with integrated high- and low-pass filters. This results in a smoother transition between the woofer and tweeter, delivering superior midrange performance.

ADVANCED ENGINEERING

The JBL GTO speaker lineup is the result of real engineering and real-world testing. This results in speakers that absolutely sound better than the competition. High output, better bass response, long life and a smooth response are what you can expect from a GTO speaker, or any other speaker that wears the JBL badge.
